Greece eSIM guide: prices, networks, tourist SIMs and island coverage

This page gathers everything eSIM Check has published about staying connected in Greece: our price survey of seven travel eSIMs, the tourist offers of Vodafone and Nova, the independent measurements of the three networks, and what to expect on the islands and on ferries. It is written for visitors from outside the EU, from the UK, the US, Canada, Switzerland, North Africa, Latin America or the Gulf. If your SIM is from an EU or EEA country, you already roam at home prices in Greece within your operator's fair-use limits and do not need any of this. Cosmote, Greece's largest operator, became Telekom in September 2026: it is the same network. Every figure is dated and every article links to its sources.

Key facts

EU and EEA SIM cards (plus Moldova and Ukraine) roam in Greece at home prices, according to the EU’s Your Europe page; UK, US, Swiss and other visitors pay their own operator's roaming rates, or use a travel eSIM or a Greek SIM.

Vodafone’s tourist page listed unlimited data in Greece plus 200 minutes for 30 days at €27, sold online with a passport or at its kiosk at Athens International Airport.
